Definitions
- the invention relates to a method of manufacturing rectangular framers, in particular window frames made of plastic shaped pieces, in which four plastic shaped pieces, cut to an appropriate length with mitres, are clamped, by using exchangeable welding shims corresponding to the piece cross-section in a four-head welding machine and are simultaneously welded with each other at all mitre surfaces under action of heat and pressure by formation of weld beads, with subsequent treatment of the frame in a cleaning, e.g., sandblast machine. In the cleaning machine, the protruding weld beads are removed.
- the invention also relates to an apparatus for effecting the inventive method.
- window frames or the like from plastic materials is effected in the following manner.
- Four plastic shaped pieces cut to a predetermined length with appropriate mitres are positioned manually one after another in a so-called four-head welding machine. Then, they are aligned and clamped together.
- the plastic shaped pieces are simultaneously heated, at their adjacent mitre surfaces, to a predetermined temperature, which is selected so that the connected mitre surfaces, after removal of the heating devices, are welded to each other by being pressed against each other, thereby forming weld beads.
- the welded window frames are transported to a cleaning machine in which the weld beads, at least in the region of visible surfaces of window frames, are treated or eliminated.
- the welding of plastic shaped pieces, with a known four-head welding machine takes place mostly in a position in which the weldable window frame is in a vertical or substantially vertical position, and in this position, is transported from the four-head welding machine to the cleaning machine.
- the main object of the invention is a method for manufacturing rectangular frames, in particular window frames from plastic materials, which can be effected in a relatively small space, without high investment expenses, while insuring the possibility of using a modern and rapid angle cleaning machine in an economical manner.
- This method permits the increase in the number of welded window frames produced in a unit of time and thereby better use of the capacity of the angle cleaning machine.
- the method as well as the apparatus for effecting the method does not require especially high additional investment expenses, and can be implemented in a very small space, mostly with available floor space capacity. It also permits a better use of operational personal, as the operator is only required to position the plastic shaped pieces, so that production costs of a window frame, which include salary expenses, are reduced.
- FIGURE of the drawing shows a schematic view of an apparatus for producing window frames from plastic materials according to the invention.
- the drawing shows schematically an automatic apparatus for producing window frames of plastic profiled pieces, which apparatus is advantageously controlled from a central computer.
- the apparatus according to the invention comprises a so-called welding roundabout installation 1 with which an angle cleaning machine, shown only schematically is connected.
- the cleaning machine 3 is connected with the welding roundabout installation by an intermediate conveyor 2 which also serves as a buffer station.
- the welding roundabout installation has a base plate, not shown in the drawing, on which, e.g., a turntable 5 is supported by a ball turning attachment.
- the turntable 5 is provided with a, per se known, drive, not shown in the drawings.
- the drive rotates the turntable 5 in the direction of arrow 6 in steps of 90°.
- the turntable 5 has a square base surface.
- the turntable 5 carries a square stand 7 formed of metal shaped pieces and having side surfaces which, when viewed upwards from below, are tilted inward by an angle of about 5-15°, so that the stand has a truncated pyramidal shape.
- At least one guide rail is fixedly secured to the stand 7 while the other guide rail is displaced parallel to the stationary guide rail by a per se known drive, not shown in the drawings. If necessary, both guide rails 8 can be made displaceable.
- Two welding units 9 are movable on their respective guide rails relative to one another. Preferably, the lower welding unit is fixedly secured to a respective guide rail, and the upper welding unit moves toward and away from the lower welding unit.
- the two upper welding units which are arranged on two guide rails 8 of one side of the stand 7, are always synchronously movable relative to the respective lower welding units 9.
- Each welding unit 9 comprises, as per se known, two clamping elements and one plate-like heating device, a so-called heated tool.
- all four sides of the stand 7 are similarly formed, such that they are provided, on each side, with two guide rails 8, each with two welding units 9 and, thus, a complete welding machine. All four welding machines are controlled from a common control station which controls the welding machines only in predetermined positions of the separate machines. Because of the square shape of turntable 5, each side of the stand 7 and, thus, each welding machine thereat can be moved successively into positions I-IV.
- the welding machine In position I, the welding machine is fitted out, e.g., manually with four plastic shaped pieces. All welding units 9, which are in the position I and are controlled by a single program, are brought into a predetermined position in which the plastic shaped pieces, which are cut to a predetermined length with appropriate mitres, are arranged and clamped together. Each welding unit 9 is equipped with so-called welding shims corresponding to a cross-section of a plastic shaped piece. Normally, for correct positioning and clamping of the plastic shaped pieces about 30-40 seconds is necessary.
- the drive of the turntable 5 is actuated, and the turntable 5, together with the stand 7, is rotated by 90°, until the clamped plastic shaped pieces are in position II.
- the heated tool is introduced between adjacent mitres, and the shaped pieces are moved by the welding units 9.
- the shaped pieces are moved in such a way that all mitre surfaces are heated to such an extent that they, after removal of the heated tools and their further movement toward each other, are welded to each other as a result of pressure applied to them. With this, the actual welding process takes place in position II of the turntable 5.
- the welded window frame In the position III of the turntable 5, the welded window frame is not subjected to any treatment. In this position, only cool-down of the welding joints takes place. In position IV of turntable 5, the clamping elements of the welding units are open, and the finished welded window frame is transferred in the per se known way to the intermediate conveyor 2. The welded window frame is then transported into angle cleaning machine 3 in which all angles of the welded window frame are simultaneously cleaned.
- the shims of the welding units 9 of a welding machine can be differently formed, so that it is possible, without replacement of shims, alternatively, in two welding machines to produce a window and a door frame, respectively.
- two angle cleaning machines 3 for the turntable 5 with the welding machines. In this case, they should be arranged at an angle of 180° to each other. If necessary, more than four welding machines can be provided on the turntable 5.
